O KINETICS AND EQUILIBRIUM Using Le Chatelier's Principle to predict the result of cha... ulfur dioxide and oxygen react to form sulfur trioxide, like this: 2502(g)+02(g-2503(9) The reaction is exothermic. Suppose a mixture of SO2, O, and SO, has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation change in composition shift in equilibrium , to the right O to the left O (none) The temperature is raised. The pressure of 02 will p o to the rigt to the left (none) The temperaturs lowered The pressure of soy will

Explanation / Answer

The options marked are correct

This is an exothermic reaction which means reaction proceeds forward (or to the right) by release of heat. This also means the backward reaction is endothermic (absorbs heat)

If the temperature is increased, heat is supplied to the system (because heat is directly proportional to temperatue) and the system will move in such a way that this increase in temperature is nullified. This means reaction will move backwards (to the left). Now moving backwards means formation of reactants from products. Hence more O2 will form and pressure of O2 goes up

If the temperature is decreased, heat is taken way from the system (because heat is directly proportional to temperatue) and the system will move in such a way that this decrease in temperature is nullified. This means reaction will move forwards (to the right). Now moving forwards means formation of products from reactants. Hence more SO3 will form and pressure of SO3 goes up
